Trixene® Aqua Blocked Isocyanates

The Trixene® Aqua range includes water-dispersed latent crosslinkers and adhesion promoters to formulate 1K or 2K stoving systems. When heated these multifunctional blocked isocyanates start crosslinking with complementary functional groups in the coating and substrate.

Blocked Isocyanate Dispersions designed for Water-based 1K Systems

Our range of water-based blocked isocyanate dispersions can be used as crosslinkers and adhesion promoters for coatings and finishes on flexible and hard substrates. The Trixene® Aqua range offers a wide pH latitude including anionic and nonionic types, which are easy to formulate with good compatibility to a range of aqueous auxiliaries and other additives. These products can be used together with our water-based Witcobond® polyurethane dispersions (PUD) to formulate 1K coatings with improved chemical resistance, coating adhesion, and robustness.


Trixene® Aqua

  • Surface and interlayer adhesion
  • Chemical, impact and wear resistance
  • Durability and weathering

Formulation benefits

  • Easy to formulate stable 1K systems under low shear
  • Applicable by e.g. spraying, dipping, roller/knife/curtain coating, brushing
  • Heat curing for controlled reactivity (no free isocyanate groups)

Trixene® Aqua waterborne blocked polyisocyanates for crosslinking and adhesing promotion

  • Easy and consistent formulate stable 1K coating and impregnation systems with controlled reactivity at advised unblocking temperature
  • Sustainable and safe water-based, low VOC and no handling of free isocyanates
  • Meet your needs with a broad portfolio of anionic and nonionic grades and technical support

 

Applications

 

Fiber sizing
Trixene® Aqua can be used in glass fiber sizing to

  • Improve strand integrity and reduce fuzz formation
  • Increase compatibility with resin matrix, e.g. PA, PES, Epoxy
  • Provide synergy with Witcobond® PUD for superior results

Textile and Fabric

  • Trixene® Aqua offer highly flexible coatings with relatively low unblocking temperature for textile and fabric coatings
  • In stoving coatings for fiber impregnation, enhancing adhesion, tensile strength and washout under severe conditions

Coatings
Trixene® Aqua blocked crosslinkers are used in coatings to

  • Increase adhesion to substrate and successive layers
  • Enhance impact, scratch and chemical resistance
  • Provide excellent color retention
